Bath spray



Nov. l5, 1949 c. T. MANVILLE ET AL BATH SPRAY Filed Feb. 18, 1946 W M al@ It is preferred to provide the spray plate with fine perforations throughout the portion within the rubber rim. Modification may be made in this respect, however, if desired. Nevertheless, inasmuch as the water entering the spray head comes in by way of a port in the side wall, so as to tend to create a stream more or less parallel to the spray plate, it is desirable to provide means controlling the ow of water in the chamber so that the water will be ejected from the different j portions of the spraying surface in a uniform manner. For this purpose we provide thev shallow chamber with a slightlydished or curving inner surface at the top of the cup-shaped member, whereby the top of the cup is in the form of a shallow dome, and we provide the chamber interiorly with stream-controlling means in the nature of deecting or hibts a localized ejection of water from the spray pla e.

In the form shown, the deiiecting means or baling means includes exible rubber walls that are integral with the structure of the rubber cup. In this particular form there are. three generally longitudinal walls 25, 26 and 21 formed integral with the ton portion of the rubber cun, the walls 25 and 26 being disposed at opposite sides respectively of the inlet port 56a and leading to the left (Fig. 4) toward the onnosite side of the cup, and the wal] 21 being disposed between the walls 25 and 26 and leading from the left-hand side of the cupl (Fig. 4,) toward the right-hand side. These walls are approximately normal to the cup top. but they are obliquely disposed with respect to the general plane of the cup, as shown in Fig. 3. As shown in Fig. 3, the intermediate wall 21 extends fromrthe lefthand side wall portion in an upward direction to a point indicated at Z8, said wallhaving a straight inclined lower edge 29. The walls 25 and 26 on the other hand extend from the right (Figs. 3 and 4) to points Scand 3l and have straight inclined lower edges 32. The walls 25 and 26 preferably diverge slightly from their bases adjacent the sides of the water inlet as shown in V Fig. 4.

In addition to these generally longitudinal walls, there is provided a lateral wall 33. This wall is also integral with the cup top, but instead of being substantially normal to the adjacent top portion of the cup it is located in a plane substantially normal to the general plane of the cup, although this wall 33 is located between the center of the cup and the inlet IEE. The wall 33 extends transversely along a chord of the circle defining the water chamber, having its ends meeting the circle. This wall is located at the inner end of the wall 21 and is integrally connected to the walls 2'5 and 25 at points intermediate of the ends of those walls. As represented in Fig. 3, the wall 33 has a straight lower edge 34 lying in a plane parallel to the plane of the spray head, and it will be observed that the lower edge 34 projects downwardly somewhat beyond the walls 25 and 26. It will also be observed that preferably the lower edge ofthe wall 33 is projected downwardly to a slight extent beyond a horizontal plane passing through the inner, upper end of the inlet I 6a (Fig. 3). It will also be noted that preferably the arrangement is as shown in Fig. 3, for example, in that, while the wall 33 is normal to a horizontal plane, the inlet duct of the spray head, including the nipple and the part of I6al lying inwardly of the ballling means which in- Vwardly in this manner.

nipple, is slightly tipped with respect to such a horizontal plane.

In operation, the walls 25 and 26 have a certain lateral confining action upon the stream of water entering from the inlet. The wall 21, when the water reaches it, has a dividing action on the body of water, -causing the water at opposite sides to be turned toward opposite sides of the cup as it rebounds. The transverse Wall 33 somewhat retards the Water turned back- On the other end, the walls33, as it projects to a certain extent into the path of the water entering from the inlet, exerts a retarding action on this water and also causes the entering water to be spread or diffused somewhat in a lateral direction or, in other words, toward the sides of the cup.

By forming the top of the cup member on a relatively shallow curve and by providing deiiecting and bailling means such as above described, the spray can be caused to be ejected from the di'erent parts of the spray plate in a substantially uniform manner, notwithstanding the fact that the inlet isat one side of the spray head and that the spray head itself isY quite shallow,

While only a single embodiment of the invention is shown, it will be understood that the invention can be embodied in various forms and that modications and changes may be made without departure from the principles of the invention or the scope of the claims.

' What we claim is:

1. A bath spray device comprising a body member formed as a shallow cup with a slightly dished bottom, the side wall of the cup having an inlet at one point in the periphery, a relatively rigid perforated spray plate disposed across the mouth portion of the body member, andmeans formed integrally with the top wall of the body member at the interior thereof acting upon the incoming waterY stream to inhibit localized ejection of water from the spray plate, said means including a pair of longitudinal walls at the side adjacent the inlet, a longitudinal dividing wall adjacent the opposite side of the cup, and a transverse wall cooperating with said longitudinal Walls, said transverse wall being located between the center of the cup and the inlet and disposed as a chord of the circle dening the water chamber, said transverse wall having a lower free edge portion disposed in a plane to intersect the projection of the water stream issuing from the inlet.

2. A bath spray device comprising a cupshaped body member and a spray plate which together form a water chamber, the water chamber having an inlet at one side of the center within the side wall of the body member, and deflecting means formed as a part of the body member, said deflecting means including two Walls integrally joined to the side wall of the cup and to the cup top and leading from the side wall at the respective sides of the inlet and adapted to conne the incoming stream of Water, said deiiecting means also including a wall adjacent the side of the cup remote from the inlet which divides the stream lengthwise and a further wall disposed transversely to the first-mentioned walls, said transverse wall being located between the center of the cup and the inlet and extending across the cup adjacent the inner end of said dividing wall and extending across the rst two walls intermediate of the ends of said rst two walls, said transverse wall being substantially normal to the general plane of the spray head and having a lower free edge pro- 5 jecting into the path of the water stream entering from the inlet.

3. A bath spray device comprising a body member formed as a shallow cup with a slightly dished bottom, the side Wall of the cup having an inlet at one point in the periphery, a relatively rigid perforated spray plate disposed across the mouth portion of the bod;7 member, and means formed integrally with the top wall of the body member at the interior thereof acting upon the incoming Water stream to inhibit localized ejection of Water from the spray plate, said means including a pair of longitudinal Walls extending from the cup side adjacent the inlet and so arranged that the water enters between said walls causing the walls to have a confining action upon the stream of Water, a longitudinal dividing Wall adjacent the opposite side of the cup causing the Water at opposite sides of said dividing Wall to be turned at right angles toward opposite sides of the cup as the water rebounds from the side wall of said cup, and a transverse wall cooperating with said longitudinal walls, said transverse wall being disposed as a chord of the circle defining the water. chamber and serving to retard the rebounding Water and further exerting a retarding action on the water entering from the inlet.
